During Edit Mode, Circle selection goes wild
I have contacted Blender Dev team and they suggested my graphic driver might cause of this problem. 
What I installed combination were:

Blender version : 2.79a &amp;
GeForce Game Ready Driver version : 391.01

This combination was not good. I upgraded/downgraded Blender but selection problem won't disappear. Then I downgraded nVidia driver from 391.01 to 388.71. Then the problem has solved, back to normal behavior. 

nVidia driver consists more than 10 components and looks like newer version of component(s) from 391.01 is still in my system. So, I am not sure which component was the reason of problem but downgrading graphic driver certainly help, if you encounter similar problems.
